Thromboxane plays an essential role in haemostasis, regulating platelet aggregation and vessel tone. In humans, it signals through the TPalpha and TPbeta isoforms that are transcriptionally regulated by distinct promoters, ...
The human thromboxane (TX)A2 receptor (TP) gene encodes two TP isoforms, TPalpha and TP beta that are regulated by distinct promoters designated promoter (Prm) 1 and Prm3, respectively. Previous studies established that ...
Both thromboxane (TX) A2 and 8-epi prostaglandin (PG) F2alpha have been reported to stimulate mitogenesis of vascular smooth muscle (SM) in a number of species. However, TXA2 and 8-epiPGF2alpha mediated mitogenic signalling ...
The human (h) TXA2 receptor (TP), a G protein-coupled receptor, exists as two isoforms, TPalpha and TPbeta, which arise by alternative mRNA splicing and differ exclusively in their carboxyl terminal cytoplasmic regions. ...
Thromboxane (TX) A2 is a potent stimulator of platelet activation/aggregation and smooth muscle contraction and contributes to a variety of pathologies within the vasculature. In this study, we investigated the mechanism ...
In humans, thromboxane (TX) A2 signals through the TPalpha and TPbeta isoforms of the TXA2 receptor that exhibit common and distinct roles. For example, Gq/phospholipase (PL)Cbeta signaling by TPalpha is directly inhibited ...
In humans, TPα and TPβ isoforms of the thromboxane A2 receptor are transcriptionally regulated by distinct promoters, designated Prm1 and Prm3. Previous investigations identified two upstream repressor regions (URR) 1 and ...
In humans, thromboxane (TX)A2 signals through the TPalpha and TPbeta isoforms of the TXA2 receptor, or TP. Herein, the RhoA effector protein kinase C-related kinase (PRK) 1 was identified as an interactant of both TPalpha ...
We have investigated the functional coupling of alpha and beta isoforms of the human thromboxane A2 receptor (TP) to Galpha16 and Galpha12 members of the Gq and G12 families of heterotrimeric G proteins in human embryonic ...
Thromboxane (TX) A2 and prostaglandin (PG) D2 mediate opposing actions in platelets and in vascular and non-vascular smooth muscle. Here, we investigated the effects of stimulation of the PGD2 receptor (DP) on signaling ...
